iTunes doesn´t recognize my iPhone 3G S

[MacBeginner]

Hello,
after installing Snow Leopard on my P55 System (Core i5 750) I wanted to sync my iPhone with my iTunes Library.
But it says that iTunes is not able to connect to my iPhone errorcode 0xE8000065.
(Sorry for my bad english)
Can anyone help me?

Change the USB port. Also make sure you are on the latest BIOS.

It's the bios version.
